To all whom lit may concern:

Be it known that I, O. ZWIETUscH, of the city and county ot' Milwaukee and State of VVisconsn, haveinvented anew and useful Improvement in Pumps; and I do hereby 'declare that the following is a full, clear, and exact descriptionVY thereof, which will enable those skilled in the art to make and use the same, reference heilig had to the accompanyin g drawings, forming part ot' this specification, in Which- Figure 1 is a perspective view; Fig. 2, a side view with the enlargement of the pistonrod broken out; Fig. 3, a. sectional view.

Similar letters of reference in each of the figures indicate corresponding parts.

The object of my invention is to produce a pump for soda-fountains, and lor other purposes handy and convenient for use.

A is the standard, to which the pump is secured; B, the pump-cylinder; C, the brake; D, `an enlargement ot' the piston-rod through or into which the brake works and is notpivoted E, the piston-rod F F, a couple of inletpipes-to which may be attached pipes leading to vessels containing articles necessary l'or making soda; G G, a couple ot' pipes with faucets to be used or not as circumstances may require; H, valve in the piston I l, piston; K, valve; L, valve in the outlet of the pump; M, cover of the stutting-box; N, connection that connects the pipes F F and G Gto the bottom of the pump; O, valve-seat in the bottom ot' the pump; P, top ot the cylinder and under part ot' stuiing-box; Q, plugin the outlet of the pump; R, outlet to the pump; S, fulcrum for the brake U; T, upper support for the piston-rod E.

Operation Connect outlet-pipe R with the vessel to he lled, and' connect as many of the pipes F F and G G to vessels containing whatever may be necessary to fill the vessel With and work the brake C. The end of brake C that enters the enlargement D on the rod E is made like a mortise or slot through it, and the end of the brake() works in and out and the rod E moves up and down perpendicular, making a very nice-working pump, and one in which a greater amount of throw can he used than in the ordinary pumps.

What I claim as my invention, and desire t0 secure by Letters Patent, is

A pump when constructed with cylinder B, handle C, working without a pin in its end, enlargement I), piston-rod E, inlet-pipes F F, and pipes and faucets G G, valve H, piston l, valve K, valve L, coverM, connection N, valveseat O, to'p P, plug Q, fulcrum S, support T, and frame A, all arranged substantially as described.
